UK Surface Water Flood Risk Depths for Spatial Planning, Present Day

UK geospatial data from the Environment Agency detailing land at risk of surface water flooding. It models flood extents and depths across three annual exceedance probabilities (0.1%, 1%, 3.3%) and seven depth bands up to over 2300mm. The dataset was last updated on 2026-05-29.

Use Cases

• Assess regional flood risk for land-use zoning based on defined annual exceedance probabilities.
• Model potential flood damage scenarios based on depth bands ranging from up to 150mm to over 2300mm.
• Inform infrastructure planning by identifying areas at risk from surface water flooding.
• Compare flood risk exposure across different probability scenarios (1 in 30, 1 in 100, 1 in 1000 year events).

Strengths

• Covers three distinct flood probability scenarios (0.1%, 1%, 3.3% AEP).
• Provides flood depth information across seven specific bands, from shallow (up to 150mm) to deep (over 2300mm).
• Sourced from the authoritative UK Environment Agency.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• The dataset is designed for indicative area-level risk, not for assessing risk to individual properties.
• Column-level documentation is absent; field semantics must be inferred after download.
